Maybe so, but most politicians need to get votes. Not all of them go as far as GWB-style "the kind of guy you could have a beer with" but they all know there's no benefit to being contemptuous of any popular entertainment.

An academic can be an ivory tower type who thinks sports matches, superhero movies, social media and star musicians are a waste of time.

But politicians who think the Superbowl is a waste of time, that star wars is for children, and that Taylor Swift's music sucks pretty quickly figures out sharing those opinions loses far more votes than it gains.
